Abstract

A clamping device has a rectangular frame (1), to the longitudinal members (4, 5) of which clamping strips (7, 8; 107, 108) are fastened. Each clamping strip is provided with a plurality of tapped holes (15) which are widened to a predetermined nominal size. Thus bolts (17) pushed through in each hole (15), grub screws (22) screwed into the holes (15), or stop bars of nominal diameter can be used for clamping and positioning the workpieces (16, 19). Owing to the fact that the actual clamping can be effected by means of the clamping strips (7, 8; 107, 108), the frame (1) can be kept very light, since it is freed in particular from clamping forces. <IMAGE>

Description

The present invention relates to a tension strip for use in a tensioning device for machine-tool workpieces within the meaning of claim 1.
If a workpiece is to be machined by means of a machine tool, it must be fixed in some way on the work table or in the working area of the machine tool. It is known to provide the machine table with cut-down nuts in which clamping bolts are moved. By means of the latter and with the help of bolted-like support elements a workpiece can be fixed on the machine table. This method is cumbersome and time-consuming and often not suitable for small workpieces.
The drawback of such a device is that only a single workpiece or several identical workpieces of exactly the same size can be tightened. Another obvious drawback is that if a frame is to be used for tightening large or many small workpieces, it must be either designed to be flexible enough to be used in the course of the workpiece, or it must be designed to be elastically stretched, but in the case of a workpiece with a very heavy load, it is necessary to use a frame which is not elastic enough to be used in the event of excessive wear and tear.
The present invention is intended to design a tensioner for use with an insert frame of the type mentioned at the outset, so that the tensioner can be held relatively easily and handily, but still has an exceptionally high resistance to elastic deformation during the clamping process, and can be used to secure and precisely insert either individual larger, even irregularly shaped, workpieces or a variety of smaller workpieces, even of different dimensions.
According to the invention, this is achieved by the features in the characteristic of claim 1.
This design allows workpieces to be clamped between two tension strips, which are adjusted roughly to the desired distance, i.e. to the width or length of the workpiece to be clamped, and temporarily fixed on either side of the frame.
The threaded holes can perform three functions: 1. to prevent the clamp bars from bending, the two holes immediately adjacent to the workpiece can be fitted with a continuous bolt, which is inserted loosely into the leaking holes and secured by a nut. 2. individual holes can be fitted with screw holes which are then tightened against the workpiece. This allows in particular the tightening of irregularly shaped or non-massive workpieces. 3. individual holes can be fitted with cylindrical attachments on which the workpiece is mounted or attached. This is particularly advantageous when several of the same workpieces in the same frame have to be tightened in succession.
The subject matter and preferred embodiments are further developed in dependent claims 2-9.
The following examples of the use of a tensioning device in accordance with the invention are explained in more detail, with reference to the accompanying drawings.

The diagram in Fig. 1 shows a frame, generally designated as a support frame, which can be fixed by means not specified on the work table (not shown) of a machine tool. Frame 1 has two transverse beams 2 and 3 and two longitudinal beams 4 and 5, which are joined together to form a rectangular rigid structure. The two longitudinal beams 4 and 5 are equipped with threaded holes 6 perpendicular to the frame plane, arranged in a row along the length of the longitudinal beams 4 and 5 at equal distances from each other.
In the example, frame 1 is equipped with a first pair of tension strips 7, 8 and a second pair of tension strips 107, 108. Their formation is clearly shown in Figures 2-4 where tension strips 7 are shown in a side view, a bottom view and a cross section, and Figures 6-8 where tension strips 107 are also shown in a side view, a bottom view and a cross section.
The length of the strip 7 without the 11 continuations is equal to the slight width of the frame 1 measured between the two length beams 4 and 5. The dimensions of the 11 continuations are such that they cover and rest on at least part of the upper sides of the 4 and 5 length beams with the threaded holes 6.
The 11 slots are equipped with longitudinal slots 12 running transversely to the 7 threaded bar, arranged so as to be above and above the threaded holes 6 of the 7 threaded bar used in frame 1. The length of the slots 12 is slightly more than the distance between the 6 threaded bar, so that each 7 or 8 threaded bar can be inserted anywhere within frame 1, parallel to the 2 and 3 cross-bearers.
The one longitudinal edge of the tension strip 7 is fitted with a number of equally spaced prismatic notches 14; between the notches 14 there is a narrow, flat area of the longitudinal edge; furthermore, the tension strip 7 is fitted with a number of holes 15 running in the frame plane, transversely to the longitudinal direction of the tension strip 7; these are each located in the narrow flat area of the longitudinal edge of the tension strip 7 between the prismatic notches. In addition, further holes 15a may be present in the area of the tension strip ends.
The formation of the holes 15 and 15a can be seen from the section shown in Fig. 4. These are threaded holes in themselves, but they are extended to a certain nominal mass n. Preferably this nominal mass is approximately between the core hole diameter k and the thread diameter g. In the example case, threaded holes 15 and 15a are equipped with a metric M10 thread with a thread diameter of 10 mm. The core hole diameter of an M10 thread is about 8.2 mm. Thus, the nominal diameter of the holes on which the threaded holes 15 and 15a are extended is 9 mm.
This training enables the use of holes 15 and 15a in three ways: firstly, M10 screws or thread bolts can be bolted in; secondly, round bars with a diameter of 9 mm can be threaded through and are safely and largely unleashed in holes 15 and 15a; and thirdly, M8 screws or thread bolts can be threaded through.
The advantage of this training is explained below, as shown in Figure 1. As an example, six cylindrical workpieces 16 are to be tightened in frame 1 with their axis transversely to the frame plane. For this purpose, the two clamping bars 7 and 8 are used in the orientation shown. The workpieces 16 are each in prismatic gaps 14 and are thus equally spaced. The clamping bar 7 can be screwed in a desired position by means of the screws 13 on frame 1. Then the clamping bar 8 is inserted in frame 1 until the attachment is attached to the workpieces 16 at these straps and is easily fixed by means of the screws 13 to the two longitudinal strokes 4 and 5.
Now, through each of the two pairs of drill bits, 15 of the two 7 and 8 M 8-bolts 17 are pierced and each is fitted with a mother 18. The latter are now drawn evenly in turn, so that the clamping strip 8, which is only slightly fixed on the sides of the frame 4 and 5, is pulled against the workpiece 16 and clamped.
The fact that a screw bolt 17 is provided on both sides immediately adjacent to each workpiece 16 avoids any elastic deformation of clamping bars 7 and 8 during the clamping operation and ensures that all workpieces 16 are securely clamped.
In the second example, a cubic workpiece 19 with an uneven surface 20 or an indeterminate shape is to be tightened; the clamping strip 107 is to be inserted into the frame 1 at a suitable place and screwed to the two longitudinal supports 4 and 5 by means of the two screws 13; a second clamping strip 108 is then loosely inserted at a distance from the clamping strip 107 slightly greater than the width of the workpiece 19.
The workpiece 19 can now be placed on the supporting plates 124 between the two beams 9 and 10 - the arrangement and formation of which will be discussed below - which determine its height and the parallel orientation to the frame level. The clamping strip 108 is then moved to a small extent against the surface 20 of the workpiece 19 and is easily fixed by means of the two screws 13 to the longitudinal supports 4 and 5 of the frame 1.
Here again, the advantage is that the bolts 17 can be placed very close to the workpieces, so that any elastic deformation of the clamping bars 107 and 108 during the clamping operation remains very low.
The diagram in Fig. 5 shows a frame with 101 designated supporting frames, which can be fixed to the work table (not shown) of a machine tool by means not specified. The frame 101 has two transverse beams 102 and 103 and two longitudinal beams 104 and 105, which are joined together to form a rectangular rigid structure. The two longitudinal beams 104 and 105 are equipped with threaded holes 106 running perpendicular to the frame level, arranged in a row along the length of the longitudinal beams 104 and 105 at equal distances from each other.
In the example, frame 101 is equipped with two identically formed clamping strips 107 and 108. Their formation is clearly shown in Figures 6-8, where the clamping strip 107 is shown in a side view, a bottom view and a cross section. The clamping strip 107 is formed by an elongated steel element with a rectangular cross section. At both ends, the clamping strip 107 has a flattened continuation 111 each. The length of the clamping strip 107 without the continuations 111 corresponds to the slight width of the frame 101 measured between the two longitudinal beams 104 and 105. The dimensions of the thread seats 111 are such that they share the upper 106 sides of the longitudinal strips 104 and 105 with the forging screens and lie at least on these sides.
The extension points 111 are fitted with longitudinal slots 112 running transversely to the tension strip 107 and arranged so as to be above and release the tension strip 107 used in the frame 101 from the threaded holes 106. The length of the slots 112 is slightly more than the distance between the threaded holes 106 so that each tension strip 107 and 108 can be inserted anywhere within the frame 101, parallel to the cross-bearers 102 and 103.
The bar 107 has a number of holes 115 running in the frame plane, in the direction of the extension of the bar 107, each of which is located in the narrow plane of the longitudinal edge of the bar 107 and is equally spaced apart. There are also other holes 123 running in planes perpendicular to the frame, in the direction of the bar 115 and between the bar and the bar. The holes 123, the precise formation of which is shown in the section in Fig. 8, have a normal thread and are used to take up clamping buckles (not shown). Finally, the bar 107 is equipped with 124 adjacent longitudinal leaflets.
The same applies to the formation of the 115 holes as to the 15 holes in the 7th strip; reference is made to the explanations given in connection with Fig. 4 which are relevant.
Returning to Fig. 5, the advantage of this second training is explained below. As an example, four cubic workpieces 116 are to be tightened into the frame 101. To this end, the clamping bar 107 is inserted into the frame 101 in a suitable place and screwed with the two screws 113 to the two longitudinal bearings 104 and 105. Then a second clamping bar 108 is inserted loosely at a distance from the clamping bar 107 approximately equal to the nominal width of the workpieces 116.
The workpieces 116 can then be placed between the two beams 107 and 108 between the beams 121 and 124, determining their height and distance from each other. The beam 108 is then moved to a small extent against the side of the workpiece 116 and is easily fixed by means of the two screws 113 to the longitudinal supports 104 and 105 of the frame 101. The drill pairs 115 of the two beams 107 and 108 m, which are closest to the ends of the workpieces 116, are then pierced through 117 8-bolts of the beam 117 and 108 m, and each mother 118 is pulled so that it is directly attached to the seabed of the beam 108. Now, in the case of the 110-blade, the beam 110 is tightened so that the beam 110 can be fixed in the workpiece 10 and 108 so that the beam 110 can be tightened in each of the beam 10 and 10 beams.
The advantage here is that the bolts 117 can be placed very close to the workpieces, so that any elastic deformation of the clamping bars 107 and 108 during the clamping operation is very small.
It is understood that several smaller workpieces of different widths can be tightened together accordingly, and the difference in dimensions can be easily compensated by deeper or shorter screws 122
The finished frame 1 and 101 fitted with the clamping bars of the invention are extremely stable at a relatively low weight due to the fact that the clamping mechanisms (bolts 17 and 117, bolts 22 and 122) can always be placed directly next to or very close to the workshop or workpieces, which allows the clamping bars to be kept relatively narrow and light. The same applies in particular to the frame supports 2, 3, 4 and 5 and 102, 103, 104 and 105 respectively, as they do not require any clamping forces at all, but only have the function of clamping bars 7 and 8 and 107 and 108 respectively, and thus the clamping pieces 16 and 19 and 116 respectively.
